FIREARM. I

t Patented July 29, 1913.

Application filed January 14,1913. Serial No. 741,897.

To aZZ whom it may concern: I

Be it-known that I, HENRY B.- FEBIGER, a citizen of the United States, residing in the city of New Orleans, parish of Orleans, State of Louisiana,'have invented a newan'd useful Firearm, of which the following is a specification. 1

My invention consists of an automatic firearm of the character disclosed in Ldtters Patent, N 0. 987,350, granted to me on March 2.1, 1911, in which the recoil of the breechblock caused by the explosion in the cartridge cocks the hammer and causes the discharge-of the shell of the exploded cartridge and the feed ofa fresh shell from the magazine.

It further. consists of improved means for admitting of the hammer being cocked and remaining so .while the trigger is in pulled position.

l t further consists of an improved safety- (Hitll which Will With absolute certainty prevent. the arm from being fired irrespective of how hard the trigger may hepulled.

It further consists of improved means for retaining the assembling-screw in place, when the -rm' is broken down and taken apart.

it further consists of other novel features of construction, alt as will be hereinafter fully set forth.

The annexed drawings and the following description set forth in detail one mechanical form tunhmiving the in vention, such deiail ronstrut-tion being; ult one'pf Various mechanical forms in which the principle of the invention may be used.

In said annexed drawings: Figure 1 represents an elevation of the right side of the frame and portions of e barrel, ft-ll't*-(lltl. and stoc-lt' of my irnprwzwl fire-arm. Fig. 2 rcpt-estrus :iu cl ration of the left shit-Jot said parts. Fig. represents an levation of a portion f the iiiili't'i. the fortend. the hi; rel portion of the receiver and the breeclr liinfli; of the firearm. Fig. 4 represents a longitudinal section on the his: in F ig. 3. 5 represents a part eieration and part longitudinal section 0" a. much of the fire-arm as embodies the tiring mechanism of the same, viewed from theleft side. Fig. 6 represents a similar part section and part elevation seen from the right side of the arm. Fig. 7 represents a transverse section on the line g 1 in Fig. 2.

Similar numerals of reference indicate corresponding parts in the figures.

-Refe ring to the drawings, the reference numeral 1 indicates the barrel of my im-- proved fire-arm, havingthe fore-end or fore- .arm, 2, secured to its under-side, and the numeral 3 indicates a part of the stock not shown in the drawings. The receiver, 4, of.

12, like the corresponding portion in the structure disclosed in the above referred to patent, and tangs 13 and 14, secured in the stock in the same manner as in said structurc. The stock-portion and barrel-portion of the receiver are secured together by engaging the tongues upon the edges of the stoclcportion in the grooves of the barrel portion, and are held clamped together by an assembling-screw, 15, passing through an enlargement, 16, upon the inner side of the wall of the stock-portion and engaging a threaded opening. 17, in the wall of the barrel portion with its threaded end, 18. The assembling-screw has a knurled-head, 19, upon its end, and has a reduced portion, 20. within the enlargement and the bore.

therein. which reduced portion is engaged y the end of a screw, passing through ll milargenieni. and into the bore. \\ll(.l'0l3 tlu' 215Wllll)llllg*S('l'tW i retained in the bore when ui'iscrewed from the threaded opening in the barrel-portion. i

The hammer, 23. pivoted upon a screw, .24. within the casing in a similar manner Lethe hammer disclosed in my Patent, No.

908,553, issued January 5, 1909, and has,

,ceiver, below and to the rear of the fulcrum for the hammer, and has a forwardly projecting sear-nose, 33, which may engage the lower sear-notch of the hammer, and a rearwardly projecting arm 34, against the end of which a trigger-spring, 35,,bears. A post, 36, is pivoted at its lower end to the rearwardly-projecting arm of the trigger and passes through a longitudinal slot, 37 in the main-spring rod, and the upper end of.

said post is movably connected by a slot,

. 68, and pin, 69, to the rear arm of an auxiliary sear, 38, the forward arm of which has a hook or shoulder, 39, adapted to engage the sear-notch in the free end of the hammer. Said auxiliary scar is fulcrumcd between two ears, 40, upon the under side of the upper tang. A spring, 4.1, in the tang bears against and depresses the forward end of the auxiliary sear. A stud, 42, is journaled in the upper tang and has an arm or cam, 43, secured to its inner end, which may be brought in between the end of the post and the tang to prevent the former from being moved upward, when the stud is turned to bring the arm in such position, and the outer end of the stud has a thumblever, 44, for turning it, which lever has a 111 45 u on its under side which ma enb7 7 a 3 gage either one of two depressions, 46, in the outer side of the upper tang, so that the stud and its safetyratch arm may be rotated to either, have'said arm between the end of the post and the tang to prevent the post from being moved when the trigger is pulled, or be swung out of the way of the post-to allow the latter to be moved.

A breech-block, 47, essentially similar to that disclosed in my Patent No. 987,350, slides in the receiver and upon the inner side of the barrel-portion of the same, and is there guided by a rib, 48, upon the wall of the barrel-p0rt1on and by a rib, 49, upon the under side of the overhang of the barrelportion engaging a rabbet, 50, in the upper corner of the block. A firing-pin, 51, is slidal le in the breech-block to have its rear end struck by the hammer when the block is in its forward position. An tlCtlOl'l-l)ttI', 52, slides in a groove 53, in the wall of the harrel-portion, beneath the breech-block, and has a stud, 54, at its rear end, which hector, 67,

engages an apertiired' car, 55, extending downward from the rear end of the breechblock to form a detachable connection between ,the latter andsaid bar. The forward.

a movable through the tube in slots, 59, in the same, and said pin bears against the forward end of a coded spring, 60, in the tube, the rear end of which spring bears against the closed rear end of the tube. The tendency of the spring willthus normally be to throw the action-bar and breech block forward. A finger-piece, (31, projects laterally from the action-bar and is movable in a slot, 62, in the wall of the barrel-portion of the receiver. An ejection opening, (33, is formed in said wall, and an ejector, (34, is pivoted in the opposite wall of the re ceiver, like in the arm of my Patent No. 987,350,, to eject theempty shell through such opening. The lu-eech-hloek has a groove, 65, in its-side, with which it slides upon the ejector. An extractor, 6G provided on the side of the forward end of the brecclrblock and projects into the side of the chamber of the barrel to extract the shell. shield or de- 1 as the breech-block recoils. ,i

is provided above and to the rear of the ejection-opening to deflect the empty shells as they are thrown out.

In practice, after a charged magazine has been inserted in the guide and it is desired to fire the arm, the action-bar and breechblock are drawn rearward by means of the fingerpiece, cocking the hammer, and again allowed to be drawn forward by the actionspring, when the breech-block will slide a cartridge off from the upper end of the magazine and push such cartridge into the chamber of the barrel, Vhen the trigger is pulled, the hammer strikes the firing-piu, igniting the charge in the cartridge, and the recoil of the exploding cartridge will throw the breechblock rearward to cock the hammer, whereupon the action-spring will again draw the breech-block forward, carrying an other fresh cartridge with it into the chamber. As the breech-block recoils, the extractor withdraws the exploded shell, and the ejector throws the same out through the ejectonopening as soon as the recoiling brecc hblock uncovers the latter. .As the action of the recoil of the action-bar and breech-block is almost instantaneous with the pulling of the trigger, and the natural tendency of the gunner is to keep his finger on the trigger after firing, the sear-nose of the trigger cannot engage the. lower scarnotch of the hammer as the latter is thrown back into cocked position, as the hammer would fly forward with the breech block, prematurely firing the cartridge. As however, the slot in theupper end of the post admits of the spring acting against the forward end of the auxiliary sear to depress it, the upper end of the hammer will slip beneath the hook upon such and the upper sear-notch will be engagedby saidhook and the hammer held in cocked position. When vnow the trigger is released by the finger, the trigger-spring will throw it forward to bring its sear-nose in contact with the lower 1 V5\end of the hammer so that it will engage the lower sear-notch of the latter when the auxiliary sear disengages the upper notch,

which will take place when the triggerspring depresses the rear arm of the released trigger, drawing the post downward, and the rear arm of the auxiliary sear with it, allowing the hammer to be thrown slightly forward and again be held by the triggersear, ready for the next shot.

The breech-block is supported from below on the rib 48 and by the ejector engaging the groove in the side of the block, and it is supported against lateral displacement when the gun is broken, by the rib 49, so

that the breech-block will not injure the breech-end of the barrel by snapping forward when no cartridge is in the chamber bv being out of alinement with the same, whic is liable to occur when such complete guidance is not present, and the breech-block will not be liable to drop out from the barrel portion when the gun is taken apart.

v By the screw provision retaining the assembling-screw in place, there is no liability of losing the latter when the gun is broken and taken apart. The safety-catch will absolutely prevent the trigger from being pulled when the hammer is cocked, as the thumb-lever must be turned at least onefourth of a revolution to relieve the cam from engagement with the upper end of the post before the trigger can be, pulled. This is of great advantage in a fire-arm which'is automatically cocked each time it is fired and in which there is no provision for letting down the hammer after it is cocked. The tongues and grooves in the front and top edges of the barrel and stock portions of the receiver serve to make tight joints between said port-ions, preventing spitting or escape of powder particles and gases while firing. I
